ANTONI KACZMASZKY, or PIPER, ALABAMA.

AUTOMATIC CHAIR-BLOWER.

To all whom it may concern:

"Be it known that I, ANTONI KAczMAszKir, subject of the Czar of Russia, residing at Piper, in the county of Bibb and State of Alabama, have invented certain new and useful Improvements in Automatic Chair- Blowers, of which the following is a specification.

This invention relates to certain new and useful improvements in automatic chair blowers. v

The primary object of this invention is to provide an automatically operated blowing attachment for rocking chairs and whereby the occupant may receive a cooling draft of air, while rocking in the chair.

A further object of the invention is to provide an air blowing apparatus automatically operated by the rocking ofa chair and arranged for directing a draft of air at a desired position relatively to the occupant seated therein.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts herein-after more fully described, illustrated in the accompanying drawings, and pointed out in the appended claim.

In the drawings forming a part of this application and in which like-designating characters refer to corresponding parts throughout the several views, Figure 1 is a side elevation of a chair provided with the present device, parts being broken away. Fig. 2 is a rear elevation thereof, the air pipe being broken and the same being illustrated in dotted lines in its adjusted position, and Fig. 3 is an enlarged detail view of a portion of the air discharging means partly in section and partly in elevation.

By referring to the drawings, it will be noted that the present device is illustrated in connection with a rocking chair 10 of substantially the usual form.

A bellows 11 is secured by means of its base plate -12 to the upper face of one of the chair rockers 13, the top movable plate 14 of the bellows having an inwardly opening air inlet flap valve 15, normally closed and opened for the admission of air, during the separating movement of the plates 12 and 14 which is accomplished by means of the expansion springs 16 positioned within the bellows and between the said plates Specification of Letters Patent.

thereof. A substantially S-Shaped operating lever 17 is centrally pivoted as at 18 to the outer face of the rocker 13 and has an inwardly extending arm 19 flatly engaging the upper face of the bellows top plate let at a point opposite the hinged end 20 thereof.

The lower corner free end 21 of the said lever normally projects below the bottom traction face of the rocker 13 when the bellows is expanded as best illustrated in Fig. 1 of the drawing and the stop pin 22 isprovided upon the rocker for limiting the rearward movement of the said end 21.

An air hose 23 is attached to the upper plate 14 of the bellows and communicates with the air chamber therein and passes through a boss 24 carried by a rear brace 25 of the chair. The back of the chair 10 has a transversely arranged bar 26 secured to the rear side thereof, the said bar being rectangular in cross section, and a block 27 is slidably mounted upon the said bar 26. i

The upper end of the air hose 23 is removably secured to a nipple 28 upon the lower side of the block 27, while a communicating bore 29 is provided within the said block and nipple and into the outer end of the said bore an air pipe 30 is screwthreaded. A flattened air nozzle 31 is adjustably attached to the air pipe 30 by means of a ball and socket joint 32 as best illustrated in Fig. 3 of the drawing, the said nozzle being adjustable as therein indicated in dotted lines, the adjustments being effected by shifting the nozzle pipe 33 upon releasing the collar 34 through the agency of the hold fast devices 35.

From this detailed description of the device, it will be seen that with the elements in their normal position as illustrated in Fig. 1, a forward rocking movement of the chair brings the arm end 21 in contact with the floor while the opposite portion 19 thereof forcibly depresses the bellows top plate 1% and thus forcing the air which is in the bellows out through the hose 23 and the nozzle 31 at a convenient point with respect to the occupant of the chair, it being understood that the nozzle mav be laterally shifted by moving the block 27 upon the guide rod 26. The flap valve 15 being closed during this deflation of the bellows, the rearward rocking of the chair or its return to its normal position allows the spring 16 to separate the bellows plates which opens the flap valve 15 and inflates the bellows with air through 'by the parting from the'spirit and Scope of the in"- 'vention as set forth in the claiin.
